NAME

cuserid − get character login name of the user

SYNOPSIS

#include <stdio.h>

char ∗cuserid (s)
char ∗s;

DESCRIPTION

cuserid() generates a character-string representation of the login name that the owner of the current process is logged in under.  If s is a NULL pointer, this representation is generated in an internal static area, the address of which is returned.  Otherwise, s is assumed to point to an array of at least L_cuserid characters; the representation is left in this array.  The constant L_cuserid is defined in the <stdio.h> header file. 

SEE ALSO

getlogin(3), getpwent(3)

DIAGNOSTICS

If the login name cannot be found, cuserid() returns a NULL pointer; if s is not a NULL pointer, a NULL character (’\0’) will be placed at s[0].
